The existing ambiguity of the notion of software engineering is mainly due to the fact that it is based on and depends on knowledge. The new definition of the term “software engineering”, proposed in this paper, encounters that fact. The main subject of discussion in the paper is how three different types of knowledge, namely declarative explicit, declarative structured (ontologies) and tacit c...

Interoperability and reuse of components and declarative knowledge are crucial to the further development of knowledge-based software. Unfortunately, it is hard to get components to interoperate and even harder to reuse other people’s work. These difficulties are often a result of incompatibilities in the knowledge models (the precise definition of declarative knowledge structures) assumed by t...

This paper presents a conceptual framework for the development of Knowledge Management (KM) systems to support experts in complex design activities. Designing a complex object is not a simple task, since it is concerned not only with problem solving issues, but also with the growing needs for capturing and managing the core knowledge involved in it. A complex object is typically made of a huge ...

Text mining is a popular methodology for building Technology Intelligence which helps companies or organizations to make better decisions by providing knowledge about the state-of-the-art technologies obtained from the Internet or inside companies. As a matter of fact, the objects or events (socalled declarative knowledge) are the target knowledge that text miners want to catch in general. Howe...

This article introduces some basic functions and architectural issues, that help to build a tool for programming conceptual models, and that is not specific for a particular problem class or problem solving method. Our work is based on the KADS-method, that had to be modified in some points, to enable declarative programming of inference knowledge as well as domain knowledge. It is shown, how k...

Models, and to a lesser extent datasets, embody sophisticated statements of environmental knowledge. Yet, the knowledge they incorporate is rarely self-contained enough for them to be understood and used – by humans or machines – without the modeller’s mediation. This severely limits the options in reusing environmental models and connecting them to datasets or other models. The notion of ‘‘dec...

An important requirement for any artificial intelligence program is its capability to understand what has been communicated to it. How does the program recognize all the potential effects when it is given a declarative sentence involving an action? There are three major bodies of knowledge that need to be learned. The first body of knowledge is the English grammar. The second body of knowledge ...
